In-the body 10 of the jack, a plunger 12 SHOE? into' eel om points ively c s to is arranged to reciprocate vertically, and has,-at th p rip y 9 said heel, and so inclined inits upper end, a driver plate 14 in sockets-in iwardly'that a-tight rand-crease is obtained Withwhich nail-drivers 16 are mounted by cylindrical 11 6 ends 18 for oscillation. Each driver, there being five illustrated, is guided within a tube. Of these, the rear tube 20 may be pivoted upon the jackbody for universal movement by a more or less globular head 22. The remaining tubes, 24, 24 for the side nails and 26, 26 for the breast-nails, are similarly pivoted by heads 22 upon movable carriers, as will be described. The mountings of all the driver-tubes and their points of connection to the driver-plate 14 are so arranged that said tubes are inclined with reference to the direction of reciprocation of the actuating plunger 12, they converging inwardly to a top-plate 28 of the jack, which plate is engaged by the heelseat-end of the insole of a shoe to be operated upon. The openings in the heads of the tubes lie in close proximity to the upper surface of the plate, the head of the tube 22 occupying a circular opening 30, while the tubes 24, 24 are movable in lateral slots 32, and the tubes 26 in rearwardly-extending slots 34.

Secured to the front or the jack-body, within the hollow portion, is a bracket 36,. in the upper rearward extension of which is an opening 38 to receive a pivot-pin common to two carrier-arms 40, 40. The rear extremities of these arms are provided with vertical sleeves 42 in which are formed sockets for the reception of the heads 22 upon the driver-tubes 24. These heads project from the upper ends of the sleeves to enter the slots 32 in the top-plate, and the lower portions furnish sufiicient clearance to permit free oscillation of the tubes as the plunger 12 reciprocates the drivers 16. To movably support the rear tubes 36, slides 44 are arranged to travel in ways 46 upon opposite sides or" the bracket 36 and have I all designs.

h to the respective slides 44. 'tensions 62 at their inner sides in which are sockets in which these tubes are mounted. The arms and slides are preferably simultaneously movable by a controlling member common to all and consisting of a slide 48. This slide 48 is shown as divided to extend at opposite sides of the bracket 36 beneath the lower ways 46, and is threaded at 50 to receive a screw 52 rotatable upon the front of the jack-body and passing q through an opening 53 in a bracket. By turning the screw the slide 48 may be shifted transversely of the jack. From the forwardly-extending arms of the slide 48 rise projections 54, 54 which enter openings 56 in links 58, articulated at 60 The slides have exhorizontal cam-slots 64, facing oppositely or toward each other. Entering these slots are pins 66 projecting oppositely from the arms 40.

In using this adjusting means for the driver- 7 tubes, the operator, when the nailing design is to be changed, rotates the screw 52 in one direction or the other. The supporting, guiding and connecting means for the tubes, as just described,

are so designed that as the controlling slide 48, 'acting through the links 58, moves the slides 44 and these, through the slots 64 and projections 66, swing the arms 40 about their pivot, the openings of the tube-h ads 22 all follow paths in which lie the points of insertion of the nails for This occurs without disturbance of the connections between the drivers 16 and the plate 14, said drivers simply oscillating about their ends 18 to assume different angular positions. Similarly, as the plunger rises and falls in its operating strokes for the insertion of the nails held in the tubes on the upper ends of the drivers, an oscillation of both the drivers and tubes is permitted by virtue of their pivotal connections.

The loader L has its block 70 carried upon one side of a slide-bar '72, which is reciprocated by power applied to a rack '74 upon its under side. The loader thus travels, as in the Benjamin patent, from a nail-receiving position beneath a distributor (not illustrated) to a nail-delivering position over the jack J. The nails are contained during this transfer in tubes 76, corresponding in number and position to the jack-tubes. The rear tube occupies an opening '78 in a supporting plate secured upon the upper surface of the loaderblock. The side and rear tubes lie in slots 82 in this plate. They all have heads 84 which rest upon the upper surface of the plate. Movable between the plate 80 and the body of the loaderblock is a positioning plate 86 which is cut away to clear the rear tube and has slots 88 intersecting the slots 82'and receiving the tubes 76. The plate 86 has a forward extension 90 with a perforated abutment member 92 rising from its end. Through an opening in this member passes a horizontal spindle 94 fixed in the front of theloaderblock. The member 92 is shown as divided, with the parts capable of being drawn together by a screw 93 so the plate 86 may be fixed in position upon the block 70. A spring 96 surrounds the spindle between the block and the plate member 92, urging the plate 86 to a normal position in which the camming eifect of its slots 88, in cooperation with the cross-slots 82 of the supporting plate, causes the tubes to be forced out to positions corresponding to the maximum nailing design. If the plate 82 is moved rearwardly against the force of the spring, the two sets of plate-slots co-operate to shift the tubes inward to extreme positions which may correspond to the minimum nailing design. These maximum and minimum settings, and those for designs between them, may be automatically governed by the tube-controlling mechanism of the jack J. For this purpose, the extension 90 of the positioning plate 86 has a lateral projection 100 to which is attached a rearwardly extending arm 102. At the end of this arm is a depending, inwardly turned finger 104. For any setting of the tubes in the jack less than the maximum design, the finger 104 may contact with an upward projection 106 at one side of the tube-controlling slide 48. This contact will hold the plate 86 against movement while the loader completes its travel over the jack. By properly proportioning the positioning elements of the loader, this may be caused to earn the tubes '76 to positions corresponding to those of the jack-tubes, with the result that when the loader comes to rest the two sets of tubes will be in registration. During the advance of the loader, the nails in the tubes will have been supported with their heads resting upon a shutter 108 pivoted beneath the block 70. A latch 110 at this time retains the shutter thus closed against the tension of a spring 112, joining the latch and shutter. To release the nails for delivery to the jack-tubes, when the loader-tubes are alined with them, the latch may be tripped by engagement with the rear of the jack. It may be reset during its return beneath the distributor by contact of the plate with a fixed element, which is not indicated in the drawing.

Generally, the operating procedure is as in any 1 inside heeling machine, as that of Benjamin.

The arrangement of jack-tubes in a nailing design best suited to the work to be operated upon may be obtained by manipulation of the screw 52,

ment104 and the jack element106 will automatically' cause the loader-tubes to conform to the chosen setting of the jack-tubes. If the operator prefers toadjust thev loader-tubes manually to a particular design, he may do so by moving the plate 86 whenthe loader is in its delivering position until the tubes 76 are alined with'the jack tubes, and then secure the plate by clamping the block 92 upon the guiding and spring-retaining spindle 94 by theaction of the screw 93.
